Title: CTM640/644 component Help!
Post by: pledg on 17:36, 19 October 21
Hi,


I need to replace a failed D510 on a CTM640 monitor it's listed as SR2M Zener Diode on the parts list.


Is there a modern equivalent part?


Would an R2KY be a good replacement? or an UF2002


Thanks

Are you really, really sure that the diode has failed? That's a 130V Zener diode, which is not only extremely difficult to destroy, but also can't be measured / tested like a normal diode. How have you confirmed that it's damaged?
